+# AGENTS Instructions
+
+This repository is a monorepo. Each library lives in a subdirectory under `libs/`.
+
+<corridor>
+
+## Corridor security analysis
+
+Before generating or modifying code, create a plan and use Corridor's `analyzePlan` tool to analyze it. Apply the resulting security guidance before writing code.
+
+</corridor>
+
+When you modify code in any library, run the following commands in that library's directory before creating a pull request:
+
+- `make format` – run code formatters
+- `make lint` – run the linter
+- `make test` – execute the test suite
+
+To run a particular test file or to pass additional pytest options you can specify the `TEST` variable:
+
+```
+TEST=path/to/test.py make test
+```
+
+Other pytest arguments can also be supplied inside the `TEST` variable.
+
+## Libraries
+
+The repository contains several Python and JavaScript/TypeScript libraries.
+Below is a high-level overview:
+
+- **checkpoint** – base interfaces for LangGraph checkpointers.
+- **checkpoint-postgres** – Postgres implementation of the checkpoint saver.
+- **checkpoint-sqlite** – SQLite implementation of the checkpoint saver.
+- **cli** – official command-line interface for LangGraph.
+- **langgraph** – core framework for building stateful, multi-actor agents.
+- **prebuilt** – high-level APIs for creating and running agents and tools.
+- **sdk-js** – JS/TS SDK for interacting with the LangGraph REST API.
+- **sdk-py** – Python SDK for the LangGraph Server API.
+
+### Dependency map
+
+The diagram below lists downstream libraries for each production dependency as
+declared in that library's `pyproject.toml` (or `package.json`).
+
+```text

+├── checkpoint-postgres
+├── checkpoint-sqlite
+├── prebuilt
+└── langgraph
+
+prebuilt
+└── langgraph
+
+sdk-py
+├── langgraph
+└── cli
+
+sdk-js (standalone)
+```
+
+Changes to a library may impact all of its dependents shown above.

-Git dependencies should use credential-free URLs. The CLI conservatively scans direct `langgraph.json` dependencies, common Python package files, uv project and lock files, and common Node.js package and lock files for HTTP Git URLs with userinfo. This check is not exhaustive: generated Docker builds can copy other files, including nested requirement or constraint files, into image layers without scanning them. For private dependencies, provide short-lived credentials through your build environment's secret-backed Git credential helper. Do not store credentials in copied files such as `langgraph.json` or `pip_config_file`.

-"""Read the status of each task from the writes recorded for a superstep.
-
-While a superstep is open, the checkpointer keeps a log of writes for each
-task in that step. Entries are added as tasks run and are only discarded when
-the whole superstep finishes and a new checkpoint is saved. When a task runs
-again, for example after being resumed, its earlier entries stay in the log.
-
-This module is the single place that turns that log into task status. Code that
-needs to know whether a task finished, which interrupts it raised, which of them
-are still waiting for an answer, or which output it produced must use
-`read_task_statuses` instead of inspecting the writes directly.
-
-The log uses two kinds of writes:
-
- Control writes describe what happened to a task: `INTERRUPT` (the task asked
-  a question), `RESUME` (answers the task has received), `ERROR`, and
-  `ERROR_SOURCE_NODE`. `INTERRUPT`, `RESUME` and `ERROR` each have a fixed slot
-  per task (`WRITES_IDX_MAP`), so a newer write of the same kind can replace an
-  older one.
- Every other write is output: channel writes, `RETURN` for functional tasks,
-  and the `NO_WRITES` marker.
-
-The rules are:
-
-1. When a task that ran finishes successfully, `PregelRunner.commit` records at
-   least one output write, adding `NO_WRITES` if the task produced no other
-   output.
-2. A task that pauses at an interrupt records only control writes.
-3. A task is therefore treated as finished if and only if it has an output
-   write.
-4. Because `INTERRUPT` is stored in a fixed slot, its recorded value is the most
-   recent question the task asked. That question is waiting for an answer only
-   while the task is unfinished.
-
-A `RESUME` write never means a task is finished: it can hold the answer to an
-earlier question while the task waits on a later one.
-
-What these rules cannot see:
-
- A task whose result came from the cache does not go through
-  `PregelRunner.commit`, so nothing is recorded for it. It reads as not
-  finished.
- A task that fails can record partial output writes along with its error. It
-  reads as finished, which is how the executor has always treated it.
- Writes recorded before rule 1 existed may describe a finished task with no
-  output using only control writes. Those tasks read as unfinished, which
-  matches how they were treated before.

-"""State reads while some tasks of a superstep are finished and others are paused.
-
-When parallel tasks each call `interrupt()` and only some of them are resumed,
-the superstep stays open. Its recorded writes then contain the old interrupt of
-each finished task next to that task's output. These tests check that state
-reads, which are rebuilt from the checkpointer, report only the interrupts that
-still need an answer.
